Filed: 1978-10-13
Abstract: PURPOSE:To enhance the low temp. toughness of a steel plate by slowly cooling a bloomed slab for refining at a low cooling rate and by heating the slab to a low temp. followed by rolling to a plate, direct hardening and tempering. CONSTITUTION:A slab of Ni-type alloy steel to be provided with low temp. toughness is bloomed, and the resulting slab for refining is slowly cooled at a cooling rate of 150 deg.C/hr or more to precipitate dissolved AlN in a finely dispersed state. The slab is heated to 1200 deg.C or below, rolled to a plate, directly hardened from a temp. immediately after the rolling without being reheated, and then tempered. The precipitated AlN remains finely dispersed and does not introduce anisotropy into toughness. The low temp. heating prevents the austenite grains from coarsening, resulting in enhanced low temp. toughness.

Inventor: TASHIRO ICHIRO
IPC: F23N1/02
Filed: 1986-06-02
Abstract: PURPOSE:To permit the coefficient of excessive air of a main burner to be held in a stable condition by a method wherein, a signal to increase the opening degree of an excessive air port damper is generated by the operation of a top burner while a primary delay circuit is provided to suppress the sudden change of the signal. CONSTITUTION:The operations of a flow rate regulating valve 5 and an opening and closing valve 8 for the fuel of a top burner are commanded by an output command 14 and a signal to increase 20%, for example, is generated by a bias generating unit 34 through the top burner operating signal of a top burner command 33 simultaneously with the using of the top burner 7 while this signal is inputted into an adder 31 slowly through a primary delay circuit 35. According to this method, a damper control signal from a function converter 30 is added with the amount of bias and the opening degree of an excessive air port damper 11 is increased in accordance with the amount of bias. Accordingly, even when the flow rate of fuel, which flows into the main burner 4, is reduced by the use of the top burner 7, the amount of air through the excesive air port 13 is increased, therefore, the coefficient of excessive air in the main burner 4 may be kept in constant substantially.

Title: Constant voltage circuit
Inventor: TABATA JIYUNICHI
IPC: G05F3/24
Filed: 1978-10-18
Abstract: PURPOSE: To reduce both the dispersion and the temperature variation factor and thus to ensure the steady supply voltage to the load by making use of the difference of the threshold voltage between the enhancement- and depletion-type MOSFET's.  
     CONSTITUTION: The voltage comparator consists of P-channel enhancement MOSFET (PEMOS) 1, P-channel depletion MOSFET (PDMOS)2, N-channel enhancement MOSFET (NMOS)3 and NMOS4 each. In this comparator, PEMOS1 and 2 function as the input gates, and the output signal is delivered through the drain of NMOS4 to control the gate of NMOS5. Thus NMOS5 supplies the constant voltage to load 6. When the load impedance features straight line 11 under the steady condition, the IDS-VDS characteristics of NMOS5 features line 13 along with the action point C and terminal voltage of load 6 featuring VSL. When the load becomes havy (straight line 12), the IDS-VDS characteristics features curve 14. And the action point becomes to E when the gate voltage lowers down to VG 2  with the terminal voltage of load 6 featuring VSL. Thus the terminal voltage is turned to the constant voltage.
